WILLIAM J'. NESBITT, LOS ANGELES, CALIFORNIA.

HEEL-CUTTING AIEPARATUS.

To all whom it may concern:

Be it known that I, WILLIAM J. NEsBrr'r, a citizen of the United States of America, residing at Los Angeles, county of Los Angeles, State of California, have invented a certain new and useful Heel-Cutting Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in heel cutting apparatus; more particularly to improvements in the apparatus which is disclosed in my application for patent filed August 23, 1915, Ser. No. 46,975, and in my Patents Nos. 1109136, 1109137, and 1109139, dated Sep. 1, 1914.

thereon the pulley 18 over which and the pulley 19 fast on the shaft 20 is mounted the band saw 21. The shaft 20 has its hearing 22 attached to a block 23 which is slidably mounted on the post 15 and can be adjusted by the screw 24 to properly tension the band saw 21. The latter passes through the guide 25 mounted on one side of the bowed portion 14 of the frame. On the other side of the bowed portion 14 mounted a screw 26 adapted to lock in adjusted position the slidably mounted stem 27 of a device carrying adjustable guide bars 28 which are disposed on opposite sides of the band saw 21. A guard plate 29 is mounted on an arm 30 on the forward end of the bowedportion 14 and is disposed adjacent to the band saw 21. The base 13 has thereon a platform 31 for the electric motor 32 the shaft 33 of which has fast thereon the sprocket pinion 34 over which and the sprocket'wheel 35 fast on the drive shaft 17 is fitted the sprocket chain 36.

The shelf 37 is provided with the longitudinal slot 38 and is secured on the lower end of the bowed portion 14 of the frame by the cap screw 39 which passes through the downwardly extending flange 40 on the rear part of the shelf 37 On the shelf 37 is mounted the platform 41 in the underside of which is screwed the headed pin or guide 42 which passes through the slot 38. The platform 41 and the shelf 37 are provided with raceways 43 in which are disposed the balls 44 for facilitating the movement of the platform on the shelf. On the platform 41 ismounted the transversely movable table 45 which has on its underside the dove tail guide 46 which is slidably fitted in a corresponding guidewayin the upper part of the platform 41. On a pivot 47 on the upper part of the table 45 is mounted the plate 48 "which is adjustable angularly to the band saw or cutter 21, and carries the heel clamp- 53 to the side of the adjustable plate 48 and the upper plate 50 is secured to the lever 54 by screws 55. The lever 54 has its forward end provided with the handle 56, and has its rear end mounted on the pivot 57 between the upright lugs 58 on therear of the adjustable plate 48. The upper or both of the plates 50 and 49 are provided with a plurality of spaced lateral projections 59 which are disposed adjacent to the curved edges 51 of the plates and have thereon the pins or teeth 60 Whose pointed ends terminate short of the curved edges 51 so as not to interfere with the latter bein quickly placed in the crease of the shoe. the projections 59 may be united on the lower plate 40 to form a continuous projection or ledge 61 but it is important to have the projections 59 on the upper plate 50 spaced from each other in order that the operator shall do quicker work by having no difficulty in seeing that the curved edge 51 of the upper plate is properly placed in th crease of the shoe.

The platform 41 is automatically locked in its forward position on the shelf 37 by the dog 62 which is mounted on a pivot 63 on the side of the platform 41 and has its forward end adapted to engage the'stop' 64 on the platform 41 and provided with a lateral projection 65 against which presses a suitable spring 66 which moves the dog 62 to have its rear end engage the forward end of the shelf 37. The dog 62 is moved out of engagement with the shelf 37 by pressing down on the lateral projection 65.

The approved means for adjusting the transversely movable table 45 on the platform 41 consists of the lever 67 which is mounted on the pivot 68 'on the underside of the platform 41 and is provided on its forward end with thehandle 69 and on its rear end with the projection 70 which extends through the curved slot 71 in the platform 41 and into the straight guideway 72 in the table. To lock the table 45 in adjusted position the dog 73 is adapted to engage the curved notched projection 74 on the underside of the platform 41. The dog 73 passes through the guide 75 ion the underside of the lever 67 and is provided with an offset portion 7 6'to which and the lever 67 is connected the spring 77. The forward end of the dog 73 is pivotally connected to the angular operating lever 78 which is pivotallymounted on the underside of the lever 67. By pressing up the forward end 79 of the angular lever 78, which is disposed adjacent to the handle 69, the

dog 73 is moved away fromthe notched projection 74. 7 One form of the improved means f0 locking the plate 48 in adjusted position consists of the angular operating lever 80 which is pivotally mounted on the lever 54 fr desired,

and is pivotally connected to one end of the link 81 which latter has on its other end the lateral projection 82 which passes through the slot 83 in the rear end of the lever 54' and carries a finger 84 which contacts with one end of the angular dog 85 which is pivotally mounted on the side of one of the lugs 58 and has on its other end the projection 86 adapted to fit in thenotches 87 of the curved rack 88 which is providedon the forward end of the extension 89 which is secured to the table 45 by the screws 90.

The Projection 86 is, raised "out of the nectjed one end of the cable 92 which passes around the sheave 93 mounted on the lever 54 and has its other end connected to the arm 94 on the pivot or shaft 95 which latter is mounted in bearings 96 on the plate 48 and'is connectedto one end of the dog 97 which has on its other endthe depending projection 98'adapted to fit in the notches 99 formed in thecurved end portion 100' of the table 45. By pressing down on the forward end of the'angular lever9l the cable 92 is pulled to move the arm 94, pivot and the dog 97 to raise the'pr'ojection 98 out of engagement with the notches '99. The

projection 98 may also be raised out of engagement with the notches 99 by lifting up the dog 97 by means of the handle ,1 O1-provided thereon. A stop 102 onthe table 45 limits the swing of the rear end portion of the plate 48 toward the band saw 21. a r Improved means for holding the band saw 21 to prevent play. of-the latter while the heel is being cut, consists of the memher 103 which is secured to the shelf 37 or other stationary part by the cap screw 104 and screws 105 and is formed with an open ing 106 to receive the bars 107'and the bar 108 which latter is disposedbetween the bars 107. The latter are adaptedto contact with the sides of the band saw and prevent side play of the latter, and the bar 108 ,w'hichis substantially. of. the same thickness as the bandsaw 21 abuts the rear end of the band saw and prevents rearward movement of the band saw. The bars 107 and 108' are adjustable and can be replaced when worn out,

and they can be locked in adjusted'position by means of the winged screw 109which is provided on the member 103 and adapted to bear against the bars 107 and 108;

From the foregoingthe manner of'use and j i the advantages of the improvedjconstruction will be apparent to those skilled in the art. It will be seen that when the motor 32 is operated to drive the band saw 21, and the heel of the shoe 52 is-engaged by the clamping means on the plate 48, the angular lever 80 may be pressed down to move the projection 86 out of the notches 87, whereupon if a straight out of the heel is to be made the plate 48 is turned on the pivot 47 to position against the stop 102 to have the side of the plate adjacent to the band saw parallel to the latter, or, if an angular cut of the heel is to be made the plate 48 is turned on the pivot d7 until the heel makes the desired angle to the band saw 21. Then the angular lever 80 is released to have the projection 86 drop into the notches 87 and lock the plate 48 in posit-ion on the table 45. With the construction shown in Fig. 8 the angular lever 91 is pressed to raise the projection 98 out of the notches 99, after which the plate 48 is turned on the pivot 47 to move it to have the heel disposed in the desired position relatively to the band saw 21, and the'angular lever 91 is then released to have the projection 98 drop back into the notches 99 and lock the plate 48 in adjusted position on the'table 45. When the latterhas been adjusted, the projection 65 of the dog 62 is. pressed to move the latter out of engagement with the shelf 37, and then the platform a1 is moved rearwardly to move the on the platform and provided with a curved slot, a lever pivotally mounted on the underside of the platform, a projection on the lever passing through the curved slot and extending into the straight slot, a curved projection provided with notches and disposed on the underside of the platform adjacent to the curved slot, a guide on the underside of the lever, an angular operating lever pivotally mounted on said lever, a dog provided with an offset portion and pivotally connected to the angular operating lever, said dog passing through the guide and adapted to fit in the notches, and a spring connected to the offset portion and to the first mentioned lever.

2. In heel cutting apparatus, the combination of a table having a part provided with notches, a plate pivotally mounted on the table, a lever pivotally mounted on the plate and provided with a slot, an operating lever pivotally mounted on said lever, a link pivotally connected to the operating lever and provided with a projection passing through said slot, an angular dog pivotally mounted on the plate and provided with a projection adapted to fit in the notches, and a finger carried by the projection on the link and adapted to engage the angular dog.

3. In heel cutting apparatus, the combination of a plate, a lever pivotally mounted on the plate, an upper plate and a lower plate adapted to fit in the crease between the heel seat and the heel of a shoe, the lower plate being mounted stationary on the first mentioned plate, and the upper plate being mounted on the lever, a plurality of spaced lateral projections on the upper plate, and

'teeth on said pro ections adapted to engage the heel to prevent forward movement of the heel when the latter is moved against a cutter, substantially as set forth.

In testimony whereof, I have signed my name to this specification at Los Angeles, county of Los Angeles, State of California, this 10th day of December A. D. 1915.
